Intro

This is an R Markdown blog template. This document will be knit to HTML to produce a webpage that will be hosted publicly via GitHub.

Test

You can include text, code, and output as usual. Remember to take full advantage of Markdown and follow our Style Guide.

Examples and additional guidance are provided below.

Take note of the the default code chunk options in the setup code chunk. For example, unlike the rest of the Rmd files we worked in this semester, the default code chunk option is echo = FALSE, so you will need to set echo = TRUE for any code chunks you would like to display in the blog. You should be thoughtful and intentional about the code you choose to display.

Images

Images and gifs can be displayed using code chunks:

“Safe Space” by artist Kenesha Sneed

This is a figure caption

You may also use Markdown syntax for displaying images as shown below, but code chunks offer easier customization of the image size and alignment.

This is another figure caption

Either way, the file path can be a local path within your project directory or a URL for an image hosted online. This syntax works for PNG, PDF, JPG, and even GIF formats.

Formatting

Customizing your blog design

As a final detail only if you have time, you can explore options for customizing the style of your blog. By default, we are using the readthedown theme from the rmdformats package (see Line 6 of this file if you want to switch out themes).

References

All data sources, any key R packages, and any other sources used in developing your blog should be cited in full in a list of references at the end of your blog. Your blog post should also link to these sources as they are discussed. You may choose any reference style as long as sources are fully cited (try to be consistent!).

Typically, references in R Markdown (and LaTeX) files are incorporated with a BibTeX database (a .bib file). You can try this approach or manually include either a numbered or alphabetized list.

Columbia University has compiled some guidance on how to cite data. Some data sources will give you the citation information to copy and paste. Use the provided citations or citation styles in those cases.

You can list R package citations with the code citation("packageName") in the console and then copy (and reformat as needed) the relevant text, e.g.,
